Z'o'aZZ whom it may concern.-

Beit known that I, FREDERICK A.

residing at Rocklsland, in the county'oi` Rock Island and State ofIllinois, and a citizen of the United States, have inventedva new anduseful Improvementin Wheel-Flows, of which the following isaspecilication, reference being had to the accompanying drawings, inwhich- Figure 1 is a plan. Fig, 2 is a side elevaxo tion, one wheel andpart ofthe axle being removed. Fig. 3is a detail, being a front'view ofa portion of the axle and an arm thereon. Fig. 4 is a modification,being a side elevation of theparts shown. Fig. 5 is a modification, I5being a planof the partsshown. Fig. 6 shows my improvement applied to 'acrank-axle, so arranged that the wheels are forward of themain-horizontal part of the axle', instead of be.- hind the saine, asshown in Fig.`1; and this 2o figure is a side elevation, one Wheel andpart ot' the axle being removed. This improvement relates to wheel-plowswhich lare provided with crank-axles.

The object of my invention is to so constructA a wheel-plow which has acrank-axle that the power otl the team will assist the operator in-raising the plow, which Iacc'omplish as illustrated in the drawings andhereinafter described.

' 3o That which I claim as new will be pointed out in the claim. v

In the drawings, A represents a crank-axle.

B B represent the wheels. C D are two plow-beams, connected with the'bent axle in any suitable manner land each Yadapted to receive a plow,.`as is common in gang-plows. i

` ais an armordownward extension from the axle A, and is permanentlysecured thereto.

bis a draftyrod, one end of which is con'- nected with the arm a and theother end is provided with a hook or other device, to which an evenermay be attached. Whentwo beams are used, the lforward endo` thisldraft-rod b mayr pass between vtwo short bars which are attached to theforward ends of thebeamsC D, and the position of the draft-rod betweenthese two short bars' may be adj usted so as to be either at the centeror to one side thereof,

' 5o for the purpose ci' changing'theline of draft,'

if desired.

HEAD,

The'plows 'are to be provided withya sujtable lever or levers and arack-or racks for the -purposesof raising and lowering the plows'- oftheteam through thedraft-rod b. connected,

as' described, with the arm a, will be to rock the crank-axle, and, asthe wheels move forward, to raise the central part of the axle and 6othe plow; but the construction is such that the l draft of the team willnot lift the Aplow out of the ground and keep it constantly raised, but"will partly countcrbalance it when in use, land hence the operator caneasily raise the plow by means of the usual lever. T he same object canbe accomplished in other ways which are substantially the-same hay@deserihc'ad-. .f- 1 ln Fig. 4 I have shown one modification, in whichc'epresents an arm extending np- 7o ward from the axle, insteadofdownward. d is a lever pivoted to a plow-beam, or between two plowbeams when two'are used, one arm of which extends above and the otherbelow such beam. e is a bar pivoted to 'the-upper ends '75 l of the armc and lever d. 'f is a'draft-rod cor- 1 responding to the draftrod b andYconnected i' with the lower end of the lever d. With this modificationthe operation is the same as vbef fore described, the tendency-of thepower-01h80. the team being 'to raise the plow through the lever d,connecting-arm e, and arm c.

In Fig. 5 I have shown another moditication, in which there are twodraft-rods, g h.'

The inner end of the draftrod g is connected. S5 withthe inclined part iof the bent axle, and.v

the innerend of the -other draft-rod is connected with the inclinedportion j of the'bent axle at alittle distance from the point"wherethese bent portions join the centralhoriziontal 9o part-of the'axle.Withthis modilcatiou the action of the team on the axle' tli-roughfthedraft-rods 'g h has a tendency to raise the plow' 'in the sanne manneras before "descri'bed. i. f

Wheeled plows are sometimes provided with 9 5 crank-axles vsoarrangedthat thejw'heels are forward of the central horizontal partgfthe axle, insteadof behind the' same. Inf such 'pl'ows the desiredresult is 'obtained' byy attach.-

ing'an arm which extends'up ard fromgthqvrgm..

axle, as illustrated in Figa-6,'iiiwliichukf'ep reseuts au arm' rig-idly secured -to thejelltll part of the Vaxle, whicl. arm extends upward,and the ofce of which arm is the same as that of a in Fig. 2. Z in thisFig. Giswthedraft'rod,

corresponding in oce withjthedraft-rodb in- Fig. 2. Vith this`constrnetion the power 0l' the team has a tendency to raise'the' plow.

My improvement is adapted t0 be used in connection with a single plow aswell as gang- `plows, no material change in construction be .inenrequired.'

What 1 claim as new, and desire to secure by Letters Patent, is asfollows:

In a; wheel-plow, a bent or crank axle, in

combination with one or more draft-rods con? substantially as specified.
